According to Microsoft’s @MajorNelson, the most recent numbers are as follows: 193,000 Xbox 360 consoles sold in the month of August, making it the 20th straight month that the Microsoft console has been the top selling device.

The Xbox 360, a device that came to market before the now also-venerable Playstation 3 has shown remarkable market resilience, selling strongly past the point in which its lifecycle might have been sunsetted.

However, on it sells. Why? The Kinect launch was key, sparking a sales burst for the console, but I would also argue that Microsoft’s work turning the device into a family and living room-centered media unit, and not strictly a gaming platform. More content, more content deals, and the Kinect bringing fresh all-ages titles have kept the aging device afloat.

What is next for the Xbox line? I could bore you with tales of the NextBox, but instead let me say this: uncertainty is more certain than guesswork at the moment. Something that shared a core with Windows ala Windows Phone 8 would not be surprising, but it’s dangerous to say more. In the meantime, Xbox may hit its 21st month of dominance in just a few weeks, meaning that it’s all, tear, grown up.
